Question

Find a single discount equivalent to following successive discounts :
of 20%, 10% and 5% in percent is

• A. $30$%
• B. $35$%
• C. $32$%
• D. $40$%

Answer 1

The correct option is C $32$%

$AssumeMP=Rs100$

After successive discounts $=100[1-\frac{20}{100}][1-\frac{5}{100}][1-\frac{10}{100}]$

Discount from Marked Price $=100-68.4=31.6$

% Discount $=\frac{31.6}{100}\times 100=31.6$
